I saw on btc.com that my tx is no longer in mempool. So i "ran" to my wallet (before thinking to check other explorers), deleted local tx and broadcasted new one, with 47sats/byte with rbf active in case i need it tomorrow.

What will happen if electrum catch that first transaction from network again?

You deleted the first transaction from Electrum and that is what matters. It should no longer be related by full nodes or in their mempools. The behavior you are seeing is just the block explorer databases keeping the old transactions cached in their systems, and the ones that are showing the second transaction are giving the correct result.

(By the way, this transaction has since been confirmed so you don't have a problem anymore.)
